If you are using TDP and have the threads set to 4 then with the archive logs it will write to 4 tapes and not necessarily join to one tape later. If they have 8 copies then you could potentially have 8 copies of 4 tapes. Do those numbers work better? Becky

Unfortunately I feel as if some people are taking advantage of me and backing up whenever and however much they want. For instance I know some people want a node setup but I'm backing off till I get more space. So what they do is create a mount point on a node that is already defined and back it up that way. We're just trying to set up SAP and do some testing. In the case of SAP we have an agreement they would only do a full to TSM once a week, Saturday, 200GB. Since they kick off their own backups, they could do it whenever they want. They do backup logs every day though. They have 8 copies so I know at least by this they are limited. Last night I see in the activity log that this node was connecting to TSM, they have 4 mount points and I could see that many sessions. I'm not sure however how much if any data they backed up since they go straight to tape. I had 170 scratch tapes in the unit yesterday morning yet this morning I only have 137. Since only 19 tapes ejected and went off site this morning, from yesterdays backups something doesn't add up. Since this node is allowed 4 mount points I would have expected to see at least 4 tapes in the SAPDB_TPOOL, yet I see only one below. Can someone explain this? This is where the bulk of the data should go, at least I thought. So hoe come the SAPREDO1 and 2 pools have so many tapes. I don't know if my understanding of how SAP works is different than how it actually does. Maybe that means I should change things???? Maybe someone can straighten me out on my setup...... Show volumeusage only lists one tape so I doubt that's right. tsm: ADSM>show volumeusage XBMS SHOW VOLUMEUSAGE started. Volume U00208 in use by node XBMS. SHOW VOLUMEUSAGE completed. The below select shows something different....which makes no sense, shouldn't they be the same??? tsm: ADSM>select node_name, volume_name, stgpool_name from volumeusage where node_name=upper('XBMS') NODE_NAME VOLUME_NAME STGPOOL_NAME ------------------ ------------------ ------------------ XBMS U00234 OFFSITE_POOL XBMS U00444 OFFSITE_POOL XBMS U00729 OFFSITE_POOL XBMS U01546 OFFSITE_POOL XBMS U01588 OFFSITE_POOL XBMS U01698 OFFSITE_POOL XBMS U00814 SAPREDO1_TPOOL XBMS U01543 SAPREDO1_TPOOL XBMS U01701 SAPREDO1_TPOOL XBMS U01274 SAPREDO2_TPOOL XBMS U01542 SAPREDO2_TPOOL XBMS U01761 SAPREDO2_TPOOL XBMS U00676 OFFSITE_POOL XBMS U01651 OFFSITE_POOL XBMS U00208 SAPDB_TPOOL Is there a select statement that will give me the amount of data any one node backed up the previous night? I do have one that is supposed to tell me this but it doesn't even return that node. Maybe because TSM is not kicking off the backup????
